We were worried about the dependability of this transmission. The rig's engine is supercharged, the axles are heavy Dana 60s, and its rolling around on 40-inch-tall tires, so the transmission was working harder than it was designed to. We used a B&M for a Hi-Tek SuperCooler with an electric fan, some high-quality synthetic Trick Shift transmission fluid, and a tranny temperature gauge as upgrades. We picked up the high-pressure hydraulic hose and fitting from Metro Fluid Connectors in Fullerton, California.
